Trang 5Introduction and PCI Data Security Standard Overview
The Payment Card Industry (PCI) Data Security Standard (DSS) was developed to encourage and enhance cardholder data security and facilitate the broad adoption of consistent data security measures globally PCI DSS provides a baseline of technical and operational requirements
designed to protect cardholder data PCI DSS applies to all entities involved in payment card processing – including merchants, processors,
acquirers, issuers, and service providers, as well as all other entities that store, process or transmit cardholder data PCI DSS comprises a
minimum set of requirements for protecting cardholder data, and may be enhanced by additional controls and practices to further mitigate risks Below is a high-level overview of the 12 PCI DSS requirements
This document, PCI Data Security Standard Requirements and Security Assessment Procedures, combines the 12 PCI DSS requirements and
corresponding testing procedures into a security assessment tool It is designed for use during PCI DSS compliance assessments as part of an entity’s validation process The following sections provide detailed guidelines and best practices to assist entities prepare for, conduct, and report
the results of a PCI DSS assessment The PCI DSS Requirements and Testing Procedures begin on page 19

Please refer to www.pcisecuritystandards.org for more information
Note: Information Supplements
complement the PCI DSS and identify additional considerations and
recommendations for meeting PCI DSS requirements – they do not change, eliminate or supersede the PCI DSS or any
of its requirements
Trang 7PCI DSS Applicability Information
PCI DSS applies wherever account data is stored, processed or transmitted Account Data consists of Cardholder Data plus Sensitive
Authentication Data, as follows:
Cardholder Data includes: Sensitive Authentication Data includes:
Primary Account Number (PAN)
The primary account number is the defining factor in the applicability of PCI DSS requirements PCI DSS requirements are applicable if a
primary account number (PAN) is stored, processed, or transmitted If PAN is not stored, processed or transmitted, PCI DSS requirements do not apply
If cardholder name, service code, and/or expiration date are stored, processed or transmitted with the PAN, or are otherwise present in the
cardholder data environment, they must be protected in accordance with all PCI DSS requirements except Requirements 3.3 and 3.4, which apply
only to PAN
PCI DSS represents a minimum set of control objectives which may be enhanced by local, regional and sector laws and regulations Additionally, legislation or regulatory requirements may require specific protection of personally identifiable information or other data elements (for example, cardholder name), or define an entity’s disclosure practices related to consumer information Examples include legislation related to consumer data protection, privacy, identity theft, or data security PCI DSS does not supersede local or regional laws, government regulations, or other legal requirements
The following table illustrates commonly used elements of cardholder and sensitive authentication data, whether storage of each data element is permitted or prohibited, and whether each data element must be protected This table is not exhaustive, but is presented to illustrate the different types of requirements that apply to each data element
Trang 8Data Element

Full Magnetic Stripe Data 2 No Cannot store per Requirement 3.2 CAV2/CVC2/CVV2/CID No Cannot store per Requirement 3.2 PIN/PIN Block No Cannot store per Requirement 3.2 PCI DSS requirements 3.3 and 3.4 apply only to PAN If PAN is stored with other elements of cardholder data, only the PAN must be rendered unreadable according to PCI DSS Requirement 3.4
PCI DSS only applies if PANs are stored, processed and/or transmitted
Trang 9Relationship between PCI DSS and PA-DSS
Use of a PA-DSS compliant application by itself does not make an entity PCI DSS compliant, since that application must be implemented into a PCI DSS compliant environment and according to the PA-DSS Implementation Guide provided by the payment application vendor (per PA-DSS Requirement 13.1)
The requirements for the Payment Application Data Security Standard (PA-DSS) are derived from the PCI DSS Requirements and Security
Assessment Procedures (this document) The PA-DSS details what a payment application must support to facilitate a customer’s PCI DSS
compliance
Secure payment applications, when implemented in a PCI DSS-compliant environment, will minimize the potential for security breaches leading to compromises of full magnetic stripe data, card verification codes and values (CAV2, CID, CVC2, CVV2), and PINs and PIN blocks, along with the damaging fraud resulting from these breaches
Just a few of the ways payment applications can prevent compliance include:
Storage of magnetic stripe data and/or equivalent data from the chip in the customer's network after authorization;
Applications that require customers to disable other features required by the PCI DSS, like anti-virus software or firewalls, in order to get the payment application to work properly; and
Vendors’ use of unsecured methods to connect to the application to provide support to the customer
The PA-DSS applies to software vendors and others who develop payment applications that store, process, or transmit cardholder data as part of authorization or settlement, where these payment applications are sold, distributed, or licensed to third parties
Please note the following regarding PA-DSS applicability:
PA-DSS does apply to payment applications that are typically sold and installed ―off the shelf‖ without much customization by software
vendors
PA-DSS does not apply to payment applications developed by merchants and service providers if used only in-house (not sold,
distributed, or licensed to a third party), since this in-house developed payment application would be covered as part of the merchant’s or service provider’s normal PCI DSS compliance
For detailed guidance on determining whether PA-DSS applies to a given payment application, please refer to the PA-DSS Requirements and Security Assessment Procedures, which can be found at www.pcisecuritystandards.org
Trang 10Scope of Assessment for Compliance with PCI DSS Requirements
The PCI DSS security requirements apply to all system components In the context of PCI DSS, ―system components‖ are defined as any network component, server, or application that is included in or connected to the cardholder data environment ―System components‖ also include any virtualization components such as virtual machines, virtual switches/routers, virtual appliances, virtual applications/desktops, and hypervisors The cardholder data environment is comprised of people, processes and technology that store, process or transmit cardholder data or sensitive
authentication data Network components include but are not limited to firewalls, switches, routers, wireless access points, network appliances, and other security appliances Server types include, but are not limited to the following: web, application, database, authentication, mail, proxy, network time protocol (NTP), and domain name server (DNS) Applications include all purchased and custom applications, including internal and external (for example, Internet) applications
The first step of a PCI DSS assessment is to accurately determine the scope of the review At least annually and prior to the annual assessment, the assessed entity should confirm the accuracy of their PCI DSS scope by identifying all locations and flows of cardholder data and ensuring they are included in the PCI DSS scope To confirm the accuracy and appropriateness of PCI DSS scope, perform the following:
The assessed entity identifies and documents the existence of all cardholder data in their environment, to verify that no cardholder data exists outside of the currently defined cardholder data environment (CDE)
Once all locations of cardholder data are identified and documented, the entity uses the results to verify that PCI DSS scope is appropriate (for example, the results may be a diagram or an inventory of cardholder data locations)
The entity considers any cardholder data found to be in scope of the PCI DSS assessment and part of the CDE unless such data is
deleted or migrated/consolidated into the currently defined CDE
The entity retains documentation that shows how PCI DSS scope was confirmed and the results, for assessor review and/or for reference during the next annual PCI SCC scope confirmation activity
Network Segmentation
Network segmentation of, or isolating (segmenting), the cardholder data environment from the remainder of an entity’s network is not a PCI DSS requirement However, it is strongly recommended as a method that may reduce:
The scope of the PCI DSS assessment
The cost of the PCI DSS assessment
The cost and difficulty of implementing and maintaining PCI DSS controls
The risk to an organization (reduced by consolidating cardholder data into fewer, more controlled locations)
Trang 11Without adequate network segmentation (sometimes called a "flat network") the entire network is in scope of the PCI DSS assessment Network segmentation can be achieved through a number of physical or logical means, such as properly configured internal network firewalls, routers with strong access control lists, or other technologies that restrict access to a particular segment of a network
An important prerequisite to reduce the scope of the cardholder data environment is a clear understanding of business needs and processes related to the storage, processing or transmission of cardholder data Restricting cardholder data to as few locations as possible by elimination of unnecessary data, and consolidation of necessary data, may require reengineering of long-standing business practices
Documenting cardholder data flows via a dataflow diagram helps fully understand all cardholder data flows and ensures that any network
segmentation is effective at isolating the cardholder data environment
If network segmentation is in place and being used to reduce the scope of the PCI DSS assessment, the assessor must verify that the
segmentation is adequate to reduce the scope of the assessment At a high level, adequate network segmentation isolates systems that store, process, or transmit cardholder data from those that do not However, the adequacy of a specific implementation of network segmentation is highly variable and dependent upon a number of factors, such as a given network's configuration, the technologies deployed, and other controls that may
be implemented
Appendix D: Segmentation and Sampling of Business Facilities/System Components provides more information on the effect of network
segmentation and sampling on the scope of a PCI DSS assessment
Wireless
If wireless technology is used to store, process, or transmit cardholder data (for example, point-of-sale transactions, ―line-busting‖), or if a wireless local area network (WLAN) is connected to, or part of, the cardholder data environment (for example, not clearly separated by a firewall), the PCI DSS requirements and testing procedures for wireless environments apply and must be performed (for example, Requirements 1.2.3, 2.1.1, and 4.1.1) Before wireless technology is implemented, an entity should carefully evaluate the need for the technology against the risk Consider
deploying wireless technology only for non-sensitive data transmission
For those entities that outsource storage, processing, or transmission of cardholder data to third-party service providers, the Report on
Compliance (ROC) must document the role of each service provider, clearly identifying which requirements apply to the assessed entity and which apply to the service provider There are two options for third-party service providers to validate compliance:
Trang 121) They can undergo a PCI DSS assessment on their own and provide evidence to their customers to demonstrate their compliance; or 2) If they do not undergo their own PCI DSS assessment, they will need to have their services reviewed during the course of each of their customers’ PCI DSS assessments
See the bullet beginning ―For managed service provider (MSP) reviews,‖ in Item 3, ―Details about Reviewed Environment,‖ in the ―Instructions and Content for Report on Compliance‖ section, below, for more information
Additionally, merchants and service providers must manage and monitor the PCI DSS compliance of all associated third-party service providers
with access to cardholder data Refer to Requirement 12.8 in this document for details
Sampling of Business Facilities/System Components
Sampling is not a PCI DSS requirement However, after considering the overall scope and complexity of the environment being assessed, the assessor may independently select representative samples of business facilities/system components in order to assess PCI DSS requirements These samples must be defined first for business facilities and then for system components within each selected business facility Samples must
be a representative selection of all of the types and locations of business facilities, as well as types of system components within selected
business facilities Samples must be sufficiently large to provide the assessor with assurance that controls are implemented as expected
Sampling of business facilities/system components for an assessment does not reduce the scope of the cardholder data environment or the
applicability of PCI DSS requirements Whether or not sampling is to be used, PCI DSS requirements apply to the entire cardholder data
environment If sampling is used, each sample must be assessed against all applicable PCI DSS requirements Sampling of the PCI DSS
Requirements themselves is not permitted
Examples of business facilities include but are not limited to: corporate offices, stores, franchise locations, processing facilities, data centers, and other facility types in different locations Sampling should include system components within each selected business facility For example, for each business facility selected, include a variety of operating systems, functions, and applications that are applicable to the area under review
As an example, the assessor may define a sample at a business facility to include Sun servers running Apache WWW, Windows servers running Oracle, mainframe systems running legacy card processing applications, data transfer servers running HP-UX, and Linux Servers running
MYSQL If all applications run from a single version of an OS (for example, Windows 7 or Solaris 10), then the sample should still include a variety
of applications (for example, database servers, web servers, data transfer servers)
When independently selecting samples of business facilities/system components, assessors should consider the following:
If there are standard, centralized PCI DSS security and operational processes and controls in place that ensure consistency and that each business facility/system component must follow, the sample can be smaller than if there are no standard processes/controls in place The sample must be large enough to provide the assessor with reasonable assurance that all business facilities/system components are
configured per the standard processes
If there is more than one type of standard security and/or operational process in place (for example, for different types of business
facilities/system components), the sample must be large enough to include business facilities/system components secured with each type
of process
Trang 13 If there are no standard PCI DSS processes/controls in place and each business facility/system component is managed through standard processes, the sample must be larger for the assessor to be assured that each business facility/system component has
non-implemented PCI DSS requirements appropriately
For each instance where sampling is used, the assessor must:
Document the rationale behind the sampling technique and sample size,
Document and validate the standardized PCI DSS processes and controls used to determine sample
size, and
Explain how the sample is appropriate and representative of the overall population
Assessors must revalidate the sampling rationale for each assessment If sampling is to be used, different
samples of business facilities and system components must be selected for each assessment
Compensating Controls
On an annual basis, any compensating controls must be documented, reviewed and validated by the assessor and included with the Report on
Compliance submission, per Appendix B: Compensating Controls and Appendix C: Compensating Controls Worksheet
For each and every compensating control, the Compensating Controls Worksheet (Appendix C) must be completed Additionally, compensating
control results should be documented in the ROC in the corresponding PCI DSS requirement section
See the above-mentioned Appendices B and C for more details on ―compensating controls.‖

Trang 20Build and Maintain a Secure Network
Requirement 1: Install and maintain a firewall configuration to protect cardholder data
Firewalls are devices that control computer traffic allowed between an entity’s networks (internal) and untrusted networks (external), as well as traffic into and out of more sensitive areas within an entity’s internal trusted networks The cardholder data environment is an example of a more sensitive area within an entity’s trusted network
A firewall examines all network traffic and blocks those transmissions that do not meet the specified security criteria
All systems must be protected from unauthorized access from untrusted networks, whether entering the system via the Internet as e-commerce, employee Internet access through desktop browsers, employee e-mail access, dedicated connections such as business-to-business connections, via wireless networks, or via other sources Often, seemingly insignificant paths to and from untrusted networks can provide unprotected pathways into key systems Firewalls are a key protection mechanism for any computer network
Other system components may provide firewall functionality, provided they meet the minimum requirements for firewalls as provided in
Requirement 1 Where other system components are used within the cardholder data environment to provide firewall functionality, these devices must be included within the scope and assessment of Requirement 1
